My go-to energy gels
I've tried loads of energy gels, but I keep coming back to these blackcurrant SiS ones. The flavour is spot on - not too sweet or artificial - and they’re smooth enough to take mid-run without needing water. I’ve had other gels that are too thick or sickly sweet, but these are just right. The consistency makes them easy to swallow, even when I’m pushing hard. They give me a steady energy boost without any sudden spikes or crashes. With 22g of carbs per gel, they keep me going on longer runs and rides without upsetting my stomach. I like that they’re isotonic, so I don’t have to chug water with them. They’re also vegan and gluten-free, which is a nice bonus. The 30-pack is great value, saving me money and the hassle of restocking all the time. I always keep a few in my running belt and cycling jersey because I know they work for me. If you need a reliable, easy-to-take gel that won’t let you down, I’d definitely recommend these.

Taste great!
A excellent product. Helps to give a boost of energy. Great tasting! We had tried the orange and blackcurrant but my son didn’t like the taste- he does like these ones. Great price too! Would recommend.

Good gel, could improve flavour
Good product. Helps with post workout cramps and keeps endurance levels going during high endurance sports. Tastes slightly bitter, but not disgusting

Mmm, gel
Amazon wouldn't post my original review because I focussed on how quickly and safely packaged the seller delivered my order, rather than a prduct review. Haven't used these specific boxes of energy gels as they're Xmas stocking presents, but I have used SiS energy gels in the past and they give me energy. Fruit salad is a nice flavour. Can highly recommend. Thumbs up, as long as you don't get gel on your thumb. Then it's a sticky thumbs up.

Highly recommended
I used these for the London marathon (twice) great for that extra boost. Don't make me feel sick like other energy gels do.

Great energy gels
Nice gels, have been using them for more than a year so far. Taste is not bad at all, easy to take in while running, and no negative side effects on digestion. The only thing to know is that you'd probably need some water right after, just to wash off sweet aftertaste

Good gels
I've had to mark the rating down as when the box arrived there was 1 gel pack missing. That being said they're vert easy to use, great taste and good value for money. The texture us stange if you're trying gels for the first time but it's nothing sickly. Perfect size to fit into a pocket for portability when out exercising. Easy on the stomach, great quality, shame the same couldn't be said for the pre dispatch checks.

I used to use Gu energy gels but recently switched to these. The flavour is good and the $ per unit is decent. The one thing I wasn't expecting is how big these are. They're easily 2-3X the size of a regular gel. This is because they're very liquid. So they're easy to drink quickly and you also get some added hydration. I really like that for my 10k runs. I'd imagine they might be a bit awkward to carry multiples for a longer run. Recommended!
